there is a very noticeable difference between diesel and lpg v8 and 3.9 on arent the most robust engine
My 3.9 returns 16mpg on petrol and 26 and a bit on gas?
The average diesel is what? 25 - 32 dependant on how lead footed the driver is?
With diesel coming in at a little more expensive than petrol per gallon the difference in cost to cover 100 miles will be negligible.
If you engage a diesel driver in conversation the first thing they will tell you about their vehicle is how cheap to run it is never how nice the ride is or how plush the interior etc
I would argue that the relatively minor cost difference at the pump is worthy of the refinement and available power for having a V8 under the bonnet. Certainly its far more relaxing traveling in relative silence rather than having to endure the row and racket produced by an equivalent diesel model.
In truth, had our discovery not come with LPG fitted to it, I wouldnt have bothered installing the system as fuel consumption has never once been on my list of priorities when choosing a vehicle. I appreciate that is not necessarily the case for everyone, however. I suppose it boils down to what you as an individual can justify or are prepared to put up with?
